Microsoft made changes to Win2K and WinXP in Service Pack 2 which causes an installation fault with the 3rd-party drivers we use for installing our PCI90 and PCI93 products. There is an updated version of the driver available from our I2C Driver Updates page - follow the link in the menu at the left of your screen.

You must fully remove the old driver using Windows System Restore, then install the updated driver.

If you are using drivers from CD version 3.9 or earlier you must download the update for PCI90/PCI93. It is also recommended that UCA93 users download an update although this is not essential.

First make sure a "busy" image is displayed - something with plenty of fine detail such as a spreadsheet or document containing small text.

Now adjust the Clock setting so that the interference is even across the screen (you will see vertical bands of interference, adjust Clock until all the bands disappear, always choose an even number, odd numbers are almost always incorrect). Now adjust Phase for the sharpest and most stable image.

You can use the Auto Adjust / Auto Setup feature to automatically set Clock and Phase if you prefer, although you may get slightly better results fine-tuning these settings manually.

Why is there noise in the black portions of the image on my LED screen when connected using the PremierViewPro-LED scaler?

You haven't set the Black Crush control.

First check the the Contrast and Black Level settings are suitable for the content of your image. To do this, go to the Input menu, to Input Settings where you can change the Contrast and Black level. Do NOT use these controls to clean up the black areas of your image, set them for best overall image quality and good greyscale rendition.

Now you should set Black Crush. To do this, go to the Output menu, select the Gamma/Col/Crush menu and then adjust the Black Crush setting to a value which cleans up your image. Typically the correct value is between 12 and 24 with a setting of 20 being optimal for many common LED screens.

VERY IMPORTANT: The Black Crush setting does NOT update in real-time. You must select a value, then press Back Up once, then select the Set Gamma/Col/Crush menu option and press Enter once. Now change "No" to "Yes" using the job wheel and then press Enter once. This causes the new values to be programmed into an eeprom in the PremierViewPro-LED.

There are a lot of numbers to calculate and program so this function typically can take 30 seconds to complete. During this time the front panel menu will show the word BUSY at the bottom right. Do not attempt to make any other adjustments while BUSY is shown.

Once programming is completed, press Back Up exit the Set Gamma/Col/Crush function.

If you are happy with the new setting you should press Back Up again to exit this menu. If you wish to change the Black Crush setting again you must adjust the value and then follow the Set Gamma/Col/Crush procedure again.

The Black Crush setting is dependent on the characteristics of your LED screen and screen control electronics so may need adjusting a little for optimum results, but once set should remain at the same value whatever the input signal type.
